- de-Qt all classes under src/common (std::string/vector/mutex, std::filesystem, expat-based XmlStreamReader/Writer) - add pure C ABI in include/common + src/common/c_api: opaque handles, init returns NULL on failure, free(NULL) is a no-op, out-params with negative OAKCOMMON_E_* error codes (include/common/error.h) - remove single-consumer classes from oakcommon (html, jobtime, otioutils, playbackaudioclock, tohex, util, avframeptr, crashpadinterface/crashpadutils, autoscroll, digit, range); their destinations are recorded in docs/zh/plans/riir/notes.md - add gtest suites under src/common/tests (127 cases), standalone build driver in src/common/standalone
